In enzymology, a mucinaminylserine mucinaminidase (EC 3.2.1.110) is an enzyme that catalyzes the chemical reaction
- D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine + H2O D-galactosyl-3-N-acetyl-beta-D-galactosamine + L-serine
Thus, the two substrates of this enzyme are D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine and H2O, whereas its two products are D-galactosyl-3-N-acetyl-beta-D-galactosamine and L-serine.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine mucinaminohydrolase. Other names in common use include endo-alpha-N-acetylgalactosaminidase, and endo-alpha-N-acetyl-D-galactosaminidase.
